Bolton boss Megson: O'Brien has big future

"Joey has got a bit of a hamstring problem," Megson told the club's official website. "We're hoping it's not too serious but we're really disappointed, both for him and for ourselves, because I thought he was our best player in the first half against Fulham.

"I think there is so much to come from the lad if we can keep him and get a real good run of games. I think he will be a real top-class performer.

"I want him to be playing in the middle of the park. He's one of those players who can do a good job at right back or centre half because he is so talented, but I see him as a midfielder."
